1. Combine the onion slices, 2 teaspoons of
the oil and ¼ teaspoon of the salt in a bowl.
2. Turn on the Cuisinart® Griddler®. Select
Smoke-Less mode and set both plates to
Beef.
3. Once preheated, put the onions on the
upper griddle plate of the Griddler®. Set
the count-up timer and cook for about 15
to 20 minutes, stirring from time to time
with a heatproof spatula, until onions are
soft. Once the onions are soft, add 1 to 2
tablespoons of water to the onions and stir
until water evaporates. Repeat until onions
are very soft and caramelized, about 10
more minutes,
adding water as needed. Remove from
griddle and reserve.
4. When the onions are just soft, form the
ground beef into 4 even-sized patties, 6
ounces each. Sprinkle both sides evenly
with the salt and pepper. Brush with the
olive oil. Add the burgers to the bottom grill
plate, and cook, about 5 minutes on each
side, or until desired doneness. Top with
cheese and transfer to plate to rest.
5. While the burgers rest, split the brioche rolls
and place onto the upper griddle plate, face
down. Cook until lightly toasted, about 2 to
3 minutes.
6. Top each burger with some of the
caramelized onions and serve in the
toasted rolls.
